S2.OP-SO.WG-0011 — Discharge of 24 Gas Decay Tank to Plant Vent
DRAFT — Reconstructed from exam materials
Purpose
Provides instructions for releasing radioactive waste gas from 24 Waste Gas Decay Tank (GDT) through the plant vent system.
Key Actions / Information
Exam — 2019 Q35
During a 24 GDT release, 2R41 Channel D High Radiation Alarm causes 2WG41 (GDT VENT CONT V) to AUTOMATICALLY close, terminating the release. Other valves open during the release (24WG34, 2WG39, 2WG38) do NOT automatically close on 2R41 high radiation — only 2WG41 receives the automatic closure signal from 2R41.
